MANTLE OR HOOD FOR WEL SBACH OR OTHER INCANDESCENT LIGHTS.

SPECIFICATION forming part of Letters Patent No. 606,224, dated June 28, 1898. Application filed December 1,1896. Serial No. 614,061. (No model.) Patentedin England January 31, 1895, No. 2,224.

To mZZ whom it may concern:

Be it known that I, JULIUS MOELLER, a subject of Her Majesty the Queen of GreatBritain, residing at IVestminster, London, England, have invented certain new and useful Improvements in Mantles or Hoods for Welsbach or other Incandescent Lights, (for which I have obtained a patent in Great Britain, No. 2,224, dated January 31, 1895,) of which the following is a specification.

Hitherto mantles, hoods, or illuminant appliances for incandescent gas lights have been manufactured by impregnating a vegetable fabric or texture, comprised of loops spun, woven, or knitted together and formed from a substantially continuous thread or threads, with solutions of certain metallic salts, and then burning the fabric or texture, leaving a skeleton of earthy oxid which when heated by a suitable burner is rendered incandescent. In the burning operation to which the appliance is subjected it undergoes considerable shrinkage, and since all the loops of which the fabric or texture consists are connected to one another and do not allow freedom for such unequal shrinkage as may result from the nature of the material it follows that the product is fragile, some parts of it being under strains which render it liable to breakage.

The object of my invention is, to provide a fabric or texture for the purposes mentioned in which all of its parts are free to shrink or take shape and position independently of each other, whereby the fabric is relieved from inequalities of strain and is consequently less liable to breakage than are the woven or knitted fabrics now employed. To this end I construct a fabric of suitable shape consisting of a number of links engaging with each other like the links of a chain or chain armor, but not positively connected to each other, each link, therefore, having freedom to change its shape or position without being dependent on the changes which other links undergo.

My invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and

scope of my invention will be more fully understood from the following description ,taken in connection with the accompanying drawings, forming part thereof, and in which- Figure 1 is a perspective View of a mantle, hood, or illuminant appliance embodying'features of my invention. Fig. 2 is a similar view illustrating a modificationin the shape of the links, and Fig.3 is a similar view illustrating a mantle of my invention provided with supplemental links for producing a roughened surface.

In the drawings, a are links, which may be made by tying or otherwise uniting the ends of a thread together,'as at at. These links pass through and engage with each other like the links of a chain or chain armor and constitute a fabric of suitable form. Theselinks are not positively connected to each other, each link therefore-having freedom to change its shape or position without being dependent on the changes which the other links undergo.

The mantle, hood, or illuminant appliance illustrated in Fig. 3 is provided with a roughened surface obtained by the use, either upon its inside or outside, or both, of supplemental links a which may be arranged singly or in groups. In use good results may be obtained by making the links of short pieces of suitable thread formed into rings and knotted after being passed through links previously formed and strung together.

It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself tothe precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An illuminant appliance for incandescent lights consisting of independentrings linked together, substantially asdescribed.

An illuminant appliance for incandescent lights consisting of independentrings linked together and provided with suppleindependent rings of thread linked together mental rings, substantially as described. substantially as and for the purpose set forth.
